Terpenes constitute a large class of plant secondary metabolites. It was once presumed that these compounds are biosynthesized by typical plant terpene synthases in all land plants. This view has changed with the identification of a new group of terpene synthase genes called MTPSLs for microbial terpene synthase-like genes. MTPSLs are structurally and phylogenetically more related to bacterial and fungal terpene synthases than to typical plant terpene synthases. They are widely distributed in nonseed plants but absent in seed plants and green algae. Much of the terpene diversity in nonseed plants is presumed to be determined by MTPSLs. Phylogenetic analysis suggests that ancestral MTPSL genes were acquired by early land plants from bacteria and fungi through horizontal gene transfer.

MTPSLs:非种子植物中的新萜烯合酶

萜烯构成一类植物次生代谢产物。曾经推测这些化合物是由所有陆地植物中典型的植物萜烯合酶生物合成的。随着为微生物类萜合酶样基因鉴定了一组称为MTPSLs的新的萜类合酶基因,这种观点发生了变化。MTPSL在结构和系统发育上与细菌和真菌萜烯合酶的关系比与典型植物萜烯合酶的关系更密切。它们广泛分布于非种子植物中,但不存在于种子植物和绿藻中。推测非种子植物中的大部分萜烯多样性是由MTPSL确定的。系统发育分析表明,祖先的MTPSL基因是由早期陆地植物通过水平基因转移从细菌和真菌中获得的。
